A team of chemists and chemical engineers at Shanghai Jiao Tong University, working with a colleague from the Chinese Academy of Sciences, both in China, has built a DNA-based programmable gate array for use in general-purpose DNA computing. In their study, reported in the journal Nature, the group overcame obstacles that had hindered the development of multipurpose DNA-based circuits and created circuits using their new process.
Schematic workflow of DPGA programming. A complex task circuit beyond the capability of a single DPGA was divided into subcircuits, for which molecular instructions were generated. Involved computing units of each subcircuit, as shown by the logical arrangement in the scheme, were called by their logical address and the function was implemented via intra-DPGA routing with molecular instructions.
In 1994, Leonard Adleman won the Turing award for his proposed use of DNA base-pairing to create a biocomputing device. Since that time, many such devices have been created. But until now, any given device could do only one thing.
that forced the strands together in desired ways, creating longer strands that together made up a DPGA. The team then added fluorescence markers to allow for viewing and keeping track of circuit formation. Testing showed that a single DPGA could be designed in a way that allowed for the creation of 100 billion unique
